The Evolution of Online Slot Machines: From Mechanical to Digital Marvels
The year 1895 was a busy one. It was the birth year of former FBI director J. Edgar Hoover. It's the year that the first-ever motion picture—Workers Leaving the Lumière Factory—was made (directed and produced by Louis Lumière and is a black-and-white, silent documentary). It is also the year that Rudolf Diesel patented the diesel engine for the first time in Germany.
And, of course, 1895 was the year in which the first-ever slot machine was invented.
It was created by car mechanic Charles Fey and required players to line up matching symbols across three reels to receive a payout. Some ideas never die, eh?
Of course, today's slot machines are infinitely more complex, with each game boasting innovative and exciting mechanics, massive win multipliers, reel modifiers, and all the other bells and whistles that make online slot play so popular.
Below, we lay out the complete evolution of the slot, from its beginnings as twisted steel to a marvel of digital code, picture-perfect pixels, and impressively immersive storylines.
A Journey Begins: The Slot Machines Tale from Lever to Click
Classic 3-reel slot machines with symbols of spades, hearts, diamonds are still very popular.
As we mentioned above, the first-ever slot machine was invented in 1895 by Fey in San Francisco - and it was dubbed the Liberty Bell, mainly thanks to the distinctive liberty bell symbol that adorned its reels. It remains a prominent symbol on many online slots today and can return big wins if they line up correctly.
Transition to Electromechanical Slots
In addition to its 2D symbols, the slot also had the world-famous lever at its side, which the player pulls to make it work. This electromechanical function has been crucial to the operation of the entire slot since its first appearance.
It works by controlling the spinning reels that contain different symbols and combinations. When a player pulls down on the lever, it activates a mechanism inside the machine that spins the reels at a high speed.
As the reels spin, they randomly stop on different symbols or combinations, determining whether the player wins or loses. The lever is essentially a physical trigger.
This method has remained ever-present throughout the history of slot machines—you can still play them in some brick-and-mortar casinos. At the same time, online game developers have used its symbology to frame their products creatively.
The Digital Revolution
It was in the late nineties that slots made the transition from pulling levers to clicking.
The production of online slots can be traced back to the development of computer technology and the Internet. With advancements in hardware and software, game developers were able to create more sophisticated and visually appealing slot games.
One pivotal technological development that influenced the production of online slots was the introduction of Random Number Generators (RNGs). These complex algorithms ensure that each spin is entirely random and unbiased, replicating the unpredictable nature of traditional slot machines.
In 1998, iGaming behemoth Microgaming (now known as Games Global) developed the first-ever online slot. Titled Cash Splash, it was a progressive jackpot slot that gave players a glimpse of the future.
It set a precedent for other companies to enter the space, and within a few years, online slots began popping up everywhere, creating a race to the top.
The Role of Software Providers
Once the race began, the market was wide open for innovators, free-thinking creators, and exciting creators to bring the industry on leaps and bounds.
Online developers started springing up. Their responsibility was to create and design casino games that can be played on various online platforms, such as desktops, smartphones, and tablets.
It's a lot of responsibility—providers are charged with understanding player preferences and market trends and incorporating new technologies. They also have to ensure that the games are fair and adhere to regulatory standards while providing the highest possible standard of gameplay.
Here are five of the most well-renowned operators currently in operation:
NetEnt
Arguably the grandfather of the modern-day slot, it is renowned for producing visually stunning and innovative slot games such as Gonzo’s Gold, Starburst, and Mega Fortune. Starburst, in particular, is remembered for changing the industry when it was released in 2012 due to its reel modifiers and minimalistic design.
Games Global
Responsible for pioneering online slot games with titles like Thunderstruck, Immortal Romance, and Mega Moolah. Their progressive jackpot game, Mega Moolah, holds the record for the largest online slot payout.
Playtech
They are known for their wide range of themed slot games such as The Avengers, Gladiator, and Age of the Gods. They have also introduced unique features such as "243 ways to win" which has become a popular trend in the industry.
Yggdrasil Gaming
A producer of visually stunning and innovative slot games such as Vikings Go Berzerk, Jungle Books, and Valley of the Gods. They have also won multiple awards.
Betsoft Gaming
A creator of 3D cinematic slot games such as Good Girl Bad Girl, The Slotfather, and Gladiator. They have pushed the boundaries of slot game graphics and storytelling, setting a new standard for the industry.
Modern Online Slots
We have come a long way since the days of matching symbols on three reels and five paylines, though there is still room in the online casino sphere for this kind of game.
However, here are some examples of modern online slot mechanics employed by industry heavyweights.
-
Grid Game Mechanics
Grid game mechanics refer to gameplay commonly found in slot games. In this style of play, the reels are replaced by a grid or matrix on which symbols can fall and form combinations. Unlike traditional slots, where winning combinations are formed from left to right, grid games typically allow wins to be made horizontally and vertically. -
Progressive Multiplier Mechanics
The player's initial win is multiplied by a certain amount each time they make consecutive wins in a single round - usually in the bonus. The progressive multiplier can continue until the player reaches the maximum multiplier allowed in the game or until they no longer land consecutive wins. This mechanic adds an extra layer of excitement and potential for big wins in slot games. -
Cluster Pay Mechanics
Cluster pay mechanics are a newer gameplay style that has recently gained popularity. In this type of play, players must form clusters of symbols instead of traditional paylines.
Clusters are formed when identical symbols touch each other horizontally or vertically; the larger the cluster, the higher the payout. This mechanic allows for more flexibility in symbol placement and can lead to multiple wins on a single spin. One famous example of this gameplay is the slot game, Aloha! Cluster Pays by NetEnt.
The Future of Online Slots
As quickly as online slots have developed in the past ten years, we will likely see horizons expand over the coming decade.
With the rise of virtual reality (VR), augmented reality (AR), and blockchain technology, the future looks bright for online slot gaming enthusiasts.
The Impact on Player Experience
While the evolution of the impending VR and AR slot experience is exciting, appropriate caution should be exercised in its development.
One primary concern surrounding the technology is its potential impact on responsible gambling practices. Responsible gambling refers to the measures put in place by industry operators and regulators to ensure that individuals engaging in gambling activities do so in a safe, secure, and sustainable manner.
The immersive nature of AR and VR technology can make players lose track of time and money spent on gambling, one of the key issues lending itself to harmful behaviours for those at risk of gambling addiction.
Players and operators must find the balance to produce an exciting yet controlled gambling experience.
Spinning Toward the Future: The Unstoppable Evolution of Slots
Exciting, inventive, and technologically jaw-dropping - the modern-day slot has morphed into a popular and engaging staple of online and brick-and-mortar casinos.
Want to see its evolution for yourself? Check out some older games - like Mega Moolah, Gonzo’s Gold, and Book Of Dead. Then, compare and contrast to modern hits, like Jammin' Jars, Hotel Yeti, and Dead Or Alive II.
The improvement in graphics and gameplay is astounding.
Remember, though, whenever you play, make sure it's responsible!
